256k X 32 Bit Fast Static Ram Module , Inc

The MCM32257B is an 8M bit static random access memory module orga- nized as 262,144 words of 32 bits. The module is a 64lead zigzag inline pack- age (ZIP) of eight MCM6229 fast static RAMs packaged in 28lead SOJ packages and mounted on a printed circuit board along with eight decoupling ca- pacitors. The MCM6229 is a highperformance CMOS fast static RAM organized as 262,144 words of 4 bits, fabricated using highperformance silicongate CMOS technology. Static design eliminates the need for external Clocks or Timing strobes, while CMOS circuitry reduces power consumption and provides for greater reliability. The MCM32257B is equipped with output enable (G) and four separate byte enable (E1 E4) inputs, allowing for greater system flexibility. The G input, when high, will force the outputs to high impedance. Ex high will do the same for byte x. PD0 and PD1 are reserved for density identification. PD0 and PD1 are con- nected to ground. These pins CAN be used to identify the density of the memory module. By Freescale Semiconductor, Inc
